The LoadLifter 5000 ULTIMATE works with your truck's existing leaf springs to provide up to 5,000 pounds of front load leveling capability while maintaining vehicle stability, leveling, and comfort whether loaded or unloaded. A closed-cell urethane foam jounce bumper is integrated into the air spring to absorb shock, reduce severe jarring on uneven roads, and protect trucks hauling heavy cargoes.
